EX cancelled plans...seemed bothered I made plans!!!

the EX called Saturday to say that his plans cancelled and he wanted to see our son. I told him that I may have plans and he seemed bothered by that. Today I called to tell him I have too much going on and would have to visit either later in the week or in 2 weeks. I vote for "in two weeks" because I have shit to do this week....including getting ready for camping. He seemed bothered that I didn't just change my plans. But too fucking bad....who plans other things to do when he sees his son only 2x a month for 2 hours each?

Today, I have the following planned: someone buying furniture, picking up and dropping of DD at my mom's, laundry, softball game. I don't know how I can fit in 2 hours to just sit in my car twiddling my thumbs, waiting for his visit to end!
